Abstract

A substrate storing container that stores substrates composed of semiconductor wafers includes: a locked portion that is arranged at a center portion of an upper wall and is locked by a lifting member that can lift a container main body; in which the locked portion includes a plate-like flange portion having a lower face that faces the upper wall and an elastically deformable elastic member provided at a lower face of the flange portion and/or at a rim portion of the flange portion; and in which the locked portion is locked by the lifting member in a state in which the elastic member is sandwiched between the flange portion and the lifting member.

First claim

The invention claimed is:

1. A substrate storing container that stores substrates composed of semiconductor wafers, the substrate storing container comprising:
a container main body including a tubular wall portion having a container main body opening portion formed at one end and the other end being closed, the wall portion including a back wall, an upper wall, a lower wall, and a pair of side walls, wherein the container main body opening portion is formed by one end of the upper wall, one end of the lower wall, and one of the ends of the side walls, wherein an inner face of the upper wall, an inner face of the lower wall, inner faces of the side walls, and an inner face of the back wall form a substrate storing space which can store a plurality of substrates and is in communication with the container main body opening;
a lid body that can be removably attached to the container main body opening portion and can close the container main body opening portion; and
a locked portion that is arranged at a center portion of the upper wall and is locked by a lifting member that can lift the container main body,
wherein the locked portion includes a plate-like flange portion having a lower face that faces the upper wall, and an elastically deformable elastic member provided at the lower face of the flange portion and/or at a rim portion of the flange portion, and
wherein an upper face of the elastic member has an engaging portion that can engage with a through-hole formed in the flange portion, and the locked portion is locked by the lifting member in a state in which the elastic member is sandwiched between the flange portion and the lifting member.

2. The substrate storing container according to claim 1 ,
wherein a lower face of the elastic member is configured by a flat face and the lifting member can abut the flat face.

3. The substrate storing container according to claim 2 ,
wherein the engaging portion is configured by the elastic member which flowed into the through-hole by insert molding the elastic member having fluidity relative to the flange portion molded.

4. The substrate storing container according to claim 1 ,
wherein a lower face of the elastic member has a plurality of convex portions and the lifting member can abut the convex portions.

5. The substrate storing container according to claim 1 ,
further comprising a rigid body having an upper face and a lower face, wherein the upper face of the rigid body is fixed to the lower face of the elastic member and the lower face of the rigid body can be abutted by the lifting member,
wherein the locked portion is locked to the lifting member in a state in which the lifting member does not abut the elastic member and the lifting member abuts the lower face of the rigid body, and the elastic member and the rigid member are sandwiched between the flange portion and the lifting member.

6. A substrate storing container that stores substrates composed of semiconductor wafers, the substrate storing container comprising:
a container main body including a tubular wall portion having a container main body opening portion formed at one end and the other end being closed, the wall portion including a back wall, an upper wall, a lower wall, and a pair of side walls, wherein the container main body opening portion is formed by one end of the upper wall, one end of the lower wall, and one of the ends of the side walls, wherein an inner face of the upper wall, an inner face of the lower wall, inner faces of the side walls, and an inner face of the back wall form a substrate storing space which can store a plurality of substrates and is in communication with the container main body opening;
a lid body that can be removably attached to the container main body opening portion and can close the container main body opening portion; and
a locked portion that is arranged at a center portion of the upper wall and is locked by a lifting member that can lift the container main body,
wherein the locked portion includes a plate-like flange portion having a lower face that faces the upper wall, and an elastically deformable elastic member provided at the lower face of the flange portion and/or at a rim portion of the flange portion,
wherein the flange portion has a convex portion at a rim, and a rim portion of the elastic member has a concave portion that can engage with the convex portion at the rim of the flange portion, and
wherein the locked portion is locked by the lifting member in a state in which the elastic member is sandwiched between the flange portion and the lifting member.
